You have discovered one of the difficulties with Android. A scrollable inside another scrollable will not scroll. Try separating your UI items into smaller views.

Add these lines of code to recover attention on listview from the scrollview

Add these lines of code to recover attention on listview from the scrollview

ListView lv = (ListView) findViewById(R.id.layout_lv);
lv.setOnTouchListener(new OnTouchListener() {
    // Setting on Touch Listener for handling the touch inside ScrollView
    @Override
    public boolean onTouch(View v, MotionEvent event) {
    // Disallow the touch request for parent scroll on touch of child view
    v.getParent().requestDisallowInterceptTouchEvent(true);
    return false;
    }
});

you are use nested Scroll view

and in this scroll view you add

fillviewport=true

and in this scroll view you add
